hi Swifbuild,
Your place seems to be a very strategic area for swiftlet farming. If everything go smooth it will produce very good results. I presume birds from other farms will migrate to your farm if they know about the existance of a farm in such rich food source area.
40 nests collected in 2 years is considered a failure. The high temperature should be the core problem. 62%RH in humidity I guess he's not using any humidifier at all? My farm's lowest humidity without humidifier on is higher than that. Mine can reach over 80%RH without humidifier at night because the place is at river side. We have exactly the same reasons to DIY swiftlet farm. Those consultrants,

Their "can" and "cannot" all based on what others are doing. If there are people using such method, it can be applied. When I come out with some new ideas are "No no" just because nobody is using it. All without any explaination.
My nesting area is about 18'x38'. They finished the horizontal planks today. I've requested for 24" vertical partitions for each lines. They were mumbling about more corners created will results in lower grade nests. Yes of course I know. My goal for the 1st year is to generate as much bird population as possible. That's why those 24" partitions I requested them to use screw on. I can easily remove them when I have satisfied population growth. My corners will all be covered by 45 degree hormone treated wood by Nest Tech. So the grade of nest on 135degree surface will be better than 90degree. The tukang kayu mumbling again! The triagle holes after the 45degree wood nailed on will become cockroach nests. They thought I haven't thought of that? Just cut some PVC carpet then gun staple them to cover those holes.
The planks I'm using is 1" thick, 6" wide. Consider standard size for swiftlet farming. 1200 feet = 1 ton. I was thinking combining 2x 1" thick 3" wide plank. Up to RM500 cheaper for a ton. But I worry those carpenter will not do a fine job at the joint part. The length of my planks consist mis of 8', 9' and 10'. They have up to max 14' but I worried too long will be a problem when carrying them up the stair. I ordered mine from those "setor kayu" where they supply woods and building materials. I ordered 904 feet cost me RM1,950. One of the question before you order planks is to ask the supplier whether the woods are dry or not. New sawed woods from trees need to keep for about a year to be completely dry. Some big sawmill have a drying room to heat up the wood to make them dry. "Setor kayu"=no way. Lower density woods will be a lot different in weight for dry and wet wood. My meranti bukit as a type of middle density wood still can feel some weight difference. They supplied me with 20% of dried wood and others are new wood. My supplier only have 1" thick wood and their price is the cheapest I can find. So no choice of other thickness. I've asked another supplier in Kota Bharu Kelantan they supply "7 hoon" wood. Include shipping to my place is RM3K/ton. My price of RM2.6K/Ton is considered very cheap for meranti bukit.
My carpenters are those old fashioned kampung men. They've no intension to travel elsewehere for more profits. From their progress in my farm I predict they will take around 1 week to finish a 20'x70' farm for only nesting plank job. Your ground floor as an office is good idea. Can monitor the farm from CCTV there.
The purpose of roving area is to cut off lights from entrance hole and the curved flight path is the make swiftlet feel their nesting area is not too easy to reach by their predators. Swiftlets need 4'to 5' to make a turn so a 6' to 10' wide should be enaugh. My farm is small so I only reserved 5' wide for roving area.
You think 14" distance between planks is narrow? My tukang kau said they've made 6'-7' before. That's too narrow. Birds will suffocate when more nests built there. Mine first 1/4 using 14" then the others i changed to 16". Dr. Chris recommended minimum 12" and Mr. Phang Kam Wah recommended 16". I think 16" is more comfortable. BTW most successful farms can't even fully occupied after 5 years.
Correct. My ceiling is those with 4'x4' asbestos ceiling boards. Above that is very high zinc roof with over 20' height. It's very hot. Above the ceiling max 35degree. Below in the farm max up to 32degree. I have covered half the ceiling top with rock wool for heat insulation. Later will fully covered and add a layer of aluminium foil which people use for insulation in big air-cond ducts. Got the foil and rock wool FOC from a company previosly doing air cond ducting jobs. They're now in closing down stage. I have 2 spinning water sprinkler to be installed on the roof later on to cool down the zinc roof. Ventilation turbines are a bit costly to install though it doesn't need any power. One of my friend installed 4 units on the roof top of his farm. 2 units jammed after 2 years. I have an infra-red thermometer to measure the ceiling boards surface temperature so I will know which part need more heat insulation.
I only hope to achieve below 30degree all day long. That's the primary goal.

The one that I had mentioned is attached with a small air pump and its electri operated. It can be loaded with staples or brad nail. Staple up to 8 mm n brad nail up to 15mm lenght. So u don't need to buy additional air compressor which is bulky n expensive. I will try to look for one this weekend n keep u informed. In the USA most people DIY their things not like here. For more info search for " nailer" on the net u will have a clear picture of it. Its cost only USD 29.99 I presume the postage is about USD 25.00 all in will be USD 55.00 .I had purchased
Fishing reels and rods on line from USA before I suppose the postage is almost the same if it's based on weight. after convertion its less than RM 200.00.
Added on May 16, 2007, 6:11 pmYa almost forgotten, Y do you choose a dog kennel style for your farm?
What about the open space concept? I heard tat the open concept attracts more new birds because it is easy for the birds to enter. Most East Coast farmers preffered the O.C. In the West Coast Like S'wan, Taiping, Penang,etc most are D.K type. I still have some reservation about both perhaps you could comment.
I'll ask the machinery shop whether they have the type of nail gun which come with mini compressor tomorrow. Otherwise I will just buy the normal nail gun. I can borrow the air compressor from a friend. Now this solved my riddle about how Nest Tech installed their 45degree planks on the corners. Because in their photos I can't see any nail heads. Confirmed they were using nail gun. The whole staple will go into the wood few mm below the surface. That's why they got a clean surface.
I chose dog kennel because my flooring in the farm is wood. No doubt open roof top style is the best. Flying swiftlets can easily see its existance. But under the hole you'll need a water catchment pool with proper drainage system. The catchment pool need to be water proof or the water might leak to the floor below. So in the buiding process the builder layed down a layer of fiber glass before cover with cement.
